TEMPORARY BINDER.

SFECIFIC'ATON forming part of Letters Patent No. 317,856, dated May 12,1885.

Application flied April 9, i884. (No maar.)

To @ZZ whom it may concern:

Be it known that we, ALFRED E. ROAOH, of Brooklyn, New York, and FRANZKROEDEL, of Hoboken, New Jersey, have invented certain new and usefulImprovements in Temporary Binders, of which the following is aspecication, reference being had therein to the accompanying drawings.

The invention relates to temporary binders for papers, particularly suchas way-bill, receipt, and delivery blanks, bills of lading, te., inwhich a few sheets generally will be required for use, and in which thesheets will be frequently changed.

The invention consists of a pair of strong covers, one of which is iiatand the other hinged, and a clamping mechanism by which the covers areheld together with the sheets or blanks, substantially as hereinafterdescribed and claimed.

The object of the invention is to incline the sheets on which a recordis to be kept within permanent and durable covers, which will fullyprotect said sheets, and at the same time leave them in condition to beeasily removed and readily replaced by other sheets.

In the drawings, Figure 1 is a plan of the securing-clamp applied to thecovers. Fig. 2 is a side elevation of the clamp and covers with insertedleaves. Fig. Sis asection through covers and clamp on line x x, Fig. 1.Fig. 4 is an elevation of an elongated form of clamp plates and studsremoved from covers. Fig. 5 is. a central cross-section of same. Fig. 6shows plate applied above and below bottom cover. Fig. 7 is amodification of the fastening-button.

The lower cover of the binder is made a little larger than the sheets tobe inclosed, as at a in the drawings. This cover is madeheavy andstrong, and of materials usual in bookbinding, as of binders7 boardcovered with leather or fabric.

A base-plate, b, is embedded in the cover, as shown in Fig. 8; or it maybe secured to the upper or lower surface oi' said cover, as shown inFig. 6. The piece b, when applied to either face of cover-piece a, maybesecured thereto by screws or rivets. The base-plate b has two pins, c c,extending from its face, as shown. These pins are long enough to extendthrough all the sheets that may be placed in the binder,

and also through the top cover and a little above the surface of thesame.

A swiveledpin or stud, d, at about the cenu ter of plate b, extends up alittle higher than thepins c, and has a turn button or head, e,.at itstop. This button or head is elongated to furnish a grasp for thefingers, but is thin enough to pass through the slot in the spring,hereinafter described. The head e is squared at e, just under theelongated portion.

The cover f f is similar to cover a in general outline, but is separatedinto two partsby a hinge-connection, g. The smaller part f back of thehinge,is perforated for the passage of the pins c o d, and may bestrengthened by the insertion or application of a metal plate throughwhich the pins may pass.

A spring-plate, h,.notched at each end, as at i i, and having a slot, k,in its center, forms a spring-clamp by which all the parts may be heldtogether. The spring is curved as clearly shown at Fig. 4. The slot 7sis long enough to permit the passage of the button or head e through itwhen turned in the proper direction, but of such width that the squaredpart e will not turn in it.

In using the binder, the piece b being iirmly secured to cover a, asmany sheets m as are needed are perforated and placed over the pins c cd. The cover f f is then placed over the pins. Next the spring 7L is soplaced that its notches twill embrace pins c c. The button c is turnedinto the position shown in Fig. 4. The spring h is then depressed in thecenter, so that the length of the button will coincide with that of theslot. Then by pressing down the middle of spring h all the parts will bepressed firmly together. Then the button e has passed through slot 7s,it is turned a quarter of a revolution,and then the spring is released.The center of the spring rises so as to embrace the squared part e ofthe button, preventing it from turning further, and the button in turnholds the spring down to its bearing, sothat all parts are firmlyclamped. To release the clamp the center of the spring is againdepressed, when the butt-on may be again turned through a quarter of arevolution, so that it can pass through the slot, and the spring 71. isthus released.

IOO

It is apparent that the entire stud d may be svviveled7 as in Fig. 5, orthe head only may turn, as in Fig. 6, and that the squared part may beeither on the stud or on the head.

I claim- 1. The combination, in a temporary binder, of a cover, a,having pins c and a bindingstud, a hinged cover perforated for thepassage of said pins and stud, and a spring-plate, constructed,asdescribed, to clamp the covers together by means of the stud and itshead, substantially as described.

2. The combination of cover a, having pins c c, and stud d, havingturn-button, the hinged cover ff', perforated as described, and thespring-plate h, slotted, as described, for the passage of the head ofthe turn-button, substantially as set forth.
